Troubleshooting IIQ to XCF Conversion

• !XCF shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted XCF image looks washed out → the source IIQ likely uses a wider color space than XCF supports
• !XCF file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted XCF looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
